Alkane production from fatty alcohols by the combined reactions catalyzed by an alcohol dehydrogenase and an aldehyde-deformylating oxygenase

ABSTRACT PsADH, an alcohol dehydrogenase originating in Pantoea sp. was characterized and found to convert a broad variety of fatty alcohols into their corresponding aldehydes, the substrates of alkane biosynthesis.

Description
Summary:ABSTRACT PsADH, an alcohol dehydrogenase originating in Pantoea sp. was characterized and found to convert a broad variety of fatty alcohols into their corresponding aldehydes, the substrates of alkane biosynthesis. By coupling PsADH with NpAD, a cyanobacterial aldehyde-deformylating oxygenase, and by optimizing the conditions of the enzyme-catalyzed reactions, we achieved a 52% conversion of 1-tetradecanol to tridecane. We further applied this system to generate alkanes ranging from C5–17. These alkanes can be used as biofuels, suggesting that introducing a suitable alcohol dehydrogenase is an effective strategy to utilize fatty alcohols for alkane production. Graphical Abstract Graphical Abstract By combining reactions catalyzed by an alcohol dehydrogenase and an aldehyde-deformylating oxygenase, we constructed an alkane biosynthesis process from fatty alcohols in Escherichia coli.
